World's Longest Immersed Tunnel Passes Milestone, But Faces Delays

August 03, 2026 — James Leggate - Engineering News-Record
Work on the $8-billion Fehmarnbelt Tunnel, which is planned to link Germany and Denmark as the world’s longest immersed tunnel, is progressing as crews achieved a milestone last month with the successful immersion of its first precast concrete element. But Danish state-owned project owner Femern A/S says the plan is now running at least two years behind schedule and the tunnel’s road and rail portions will open in two separate stages.

In the Eye of the Beholder: Court of Appeal Finds Duty of Care Owed by Owner and Contractors for Death of Minors Caused by Independent Truck Driver

May 05, 2026 — Garret D. Murai - California Construction Law Blog
I was a T.A. for my high school history teacher, a really smart and nice guy, Mr. Reynolds. In the room at the back of the classroom which served as his office he had the picture above. It’s called “My Wife and My Mother-in-Law” and is taken from a German postcard from 1888. Depending on how you look it, you might see fashionable young lady, or an old lady. Cases can sometimes be like that: You see what you want to see. The next case is also like that. In Lorenzo v. Calex Engineering, Inc., 110 Cal.App.5th 49 (2025), the 2nd District Court of Appeals reversed a motion for summary judgment granted in favor of an owner and its contractors in a case involving the death of two minors struck by a dump truck enroute to a non-permitted off-site staging area.

USDOT’s DBE Interim Final Rule: How It Affects Current and Out-to-Bid DOT and Airport Projects

June 15, 2026 — Zachary F. Jacobson - The Construction Seyt
In our April 16, 2026 post, we discussed the U.S. Department of Transportation’s Interim Final Rule (IFR) concerning Disadvantaged Business Enterprise (DBE) and Airport Concession Disadvantaged Business Enterprise (ACDBE) certification, specifically as it concerns transportation and airport projects in California. This post addresses a broader question: What does the IFR mean for current and out-to-bid DOT projects operating under pre-existing DBE goals? The answer is that the IFR did more than change who qualifies as a DBE. It also changed how federally funded transportation and airport projects must be handled during the re-evaluation period. This affects active contracts, pending procurements, airport projects, design-build teams, and anyone relying on old assumptions about DBE goals and counting of DBE and ACDBE credit.

Two Important Points Regarding the Miller Act

September 15, 2026 — David Adelstein - Florida Construction Legal Updates
A recent Miller Act case, U.S. f/u/b/o Boundless Management Outsourcing Group, LLC v. Endurance Assurance Corp, 2026 WL 2241491 (D. Puerto Rico 2026), confirms two important points when it comes to the Miller Act. In this case, a subcontractor pursued a Miller Act payment bond lawsuit more than one year after its work was finished. The subcontractor also asserted a claim against the federal government. The lawsuit was dismissed. Below are two takeaway points to consider if you are dealing with a Miller Act payment bond lawsuit. First, as it relates the claim against the federal government, the federal district court followed authority that held that the Miller Act does NOT include a waiver of sovereign immunity against the federal government. “[T]he Court does not identify any clear language in the Miller Act expressly waiving the United States or its agencies’ sovereign immunity.” Endurance Assurance Corp., supra at *3.

Presumption of Prejudice Applies to All Affirmative Defenses Regarding Insured’s Failure to Comply with Post-Loss Policy Conditions

June 23, 2026 — David Adelstein - Florida Construction Legal Updates
n a recent property insurance coverage dispute, an issue on appeal pertained to the “prejudice” jury instruction associated with the insured’s failure to comply with post-loss policy conditions. The trial court found that the prejudice only pertained to prompt notice and not other post-loss policy conditions. This was reversed on appeal as prejudice applied to ALL the post loss policy conditions that the insured failed to comply with, not just the prompt notice requirement. The prejudice presumption applies to all affirmative defenses regarding an insured’s failure to comply with post-loss policy conditions. Consider this discussion when dealing with an insurer raising prejudice as an affirmative defense to do an insured’s failure to comply with post-loss policy conditions, and the associated burdens of proof: On appeal, [the insurer] contends the trial court erred by instructing the jury that the presumption of prejudice was inapplicable to all of its post-loss obligation defenses except prompt notice. We agree. Read the full story...

GRSM Secures Illinois Appellate Victory for Architectural Firm in Implied Warranty Dispute

May 14, 2026 — Gordon Rees Scully Mansukhani
Gordon Rees Scully Mansukhani Partner Jonathan Federman, Partner Thomas Cronin, and Senior Counsel Garrett Lee recently secured a victory in the Illinois Appellate Court, Fifth District, on behalf of the firm’s client, an architectural firm, in a liability dispute. The case arose following an entity’s purchase of a 111-unit building for use as an investment or rental property. The plaintiff made claims against the architect of the building, alleging that there were design defects that breached an implied warranty, as well as a negligence claim. GRSM argued that an architect could not be liable for implied warranties, particularly for an implied warranty which no Illinois court has ever recognized. GRSM further argued that Illinois law bars an architect from liability for negligence arising from a duty pursuant to contract under the economic loss doctrine. Read the full story...

Urban Digital Twins: How Virtual Cities Could Help Build Smarter Cities

August 11, 2026 — Gravel2Gavel Construction & Real Estate Law Blog
Traffic congestion, endless construction, flooded streets and power outages. For city leaders and residents alike, these disruptions are simply part of daily urban life. But an emerging tool, known as the urban digital twin, could help cities anticipate problems before they occur by allowing planners to simulate responses, stress-test infrastructure, and evaluate decisions before implementing them in the real world. What Is an Urban Digital Twin? An urban digital twin is a dynamic, data-driven virtual model of a real city. It uses AI analytics and combines 3D modeling with real-time data and information from sources such as IoT sensors, traffic cameras, satellite feeds, infrastructure databases, utility networks, and environmental data including weather systems and heat maps to create a continuously updated digital representation of the urban environment that mirrors infrastructure, movement and systems in real time. In other words, it is a living digital replica of a city. Read the full story...
